A few answers to various problems:
To Axel Kowald, who wanted to use FindRoot and NIntegrate. The
following will alleviate the problem:
FindRoot[Evaluate[NIntegrate[N[r x], {x,0,3}]==9], {r,1}]
It balks about non-numerical at... but the correct answer is produced.
To Doug Burkhardt:
Matrix multiplication is accomplished using .
a.b will matrix multiply to matrices. The answer is sometimes
transposed from the traditional way of viewing matrices but it is correct.
BTW, a b will multiply each entry of a by the corresponding entry of b.
To Chris:
To turn off the speling errors message, issue the following command:
Off[ General::spell, General::spell1 ]
A good place to put this command is in the init.m file in your
Mathematica directory.
Hope these help,
Daryl
